Application filed July 3, 1916. Serial Ito. 107,397.

To allrwhom it may concern Be it knownh t I, AR E- Sau ers, a citizen ofthe United Statesof America, residing at Atlantic, and State of Iowa, have invented certain Batt ns, f which the following is aspecifieation. My invention relates to improvements in sheet-metal battens for closing the narrow spaces between the adj aeent edges of roof boardsdisposed lengthwisea pand down the roof slope; and the objects ofmy improvement are, first, to provide-double crush sealing-joints for eachside half oi:the batten,

--tightly joining it with the board on that 1 objects,

side second, to .facilitatethe permanence of an efficient attachment, preventingrattle and leakage; and, third, to conserve the joints by an eliective draina e. All ofwhioh with others hereinaiter particularly, disclosed, 'I attain bythe construction illustrated in the accompanying drawing, .in Which-' q Figure 1=is a sectionaland top perspective view of a fragment of roofeovering, show ing the hattenapplied; Fig. 2, an underside fragmental ylew, clr 'm n at smaller scale; and F g. 3, a eross-sect1on, on the broken line 3 of Fig. 2,Yshowing'theinornial shape ofthe battenbefore it is nailed onto the roof.

Similar numerals rei er to similar parts throughout the several views.

'Ihebatten, made from .an'ar-row strip of sheetanetal has a central longitudinal portion bent downwardly to form the open gutter 2, of shape approximating a wedge or half-elliptical form .in cross-section. The

gutter is flankedat eachside by the longi-' tudinal side portions or plain sides and 4- --inte', rrally joined thereto by the short parallelly disposed bends 5 and These opposite plain sides normally stand in the same plane, as shown inl ig. 2. Narrow out side edge portions of the plain sides are bent dowm-vardly to form the cross-sectionally inclined flanges 6 and '6; their thin edges preferably standing outwardly and do'wnwai-dly as shown. Rows of punctures or perforations 7, 7, etc., to posit and receine the attaching nails 8, are disposed longitudinally of the planes and intermediately of the gutter, and flanges. Londucive to lateral elasticity of the batten, facilitating cldse fitting thereof on the face of the boards,

In. application, the roofboards 9 are first aid, pa i i i the backof the gutter fac l tates its nsertion into the space 10,;t0 properly place the batten. Foroingthe gutter clear down into the space finally brings thebaeks ofrthe bends Sand 5 or base of the rigid wedge-shaped rib 2 against the angles 11 and .11 of the .roofeboards; these sharp angles are easily crushed down by the opposed wedging sides ofthe rib on theback, to thegutter, or theimposed as shown in Fig. 1, the sh of the'fianges 6,

It is obvious, that this elastic connection retains the oints incontinuous pressure, and aizoidsnny-loosening of the battfi, should the nail be slightly started by expansion or. contraction of the connected parts caused by changes of temperature or moisture. The. batten, ha"- ing the narrowest possiblelines of contact with the boards renders these joints most effective for tightness. The opposite plain sides of the seated batten are inclined toward the central gutter, thus leading the water away from the outer joint and down the gutter. If perchance, a leak occurs, either through the outer joint or around a nail, it is carried down and out through the soace l l between the plain side of the imposed batten and the subjacent roof-hoard. The nails, being disposed remotely from the outer or weather edge of the batten, are nearly alwaysseated in dry wood and not frost or other ail'ected in their service by either moisture or boards spaced apart, in combination with a sheet-metal batten having a portion bent downwardly to form a longitudinalcentral open gutter on its face and a corresponding rigid wedge-shaped rib on its back forced into the space between said boards to crush the adjacent angles thereof and form watertight joints at each side of said rib, opposite plain longitudinal side portions of the batten inclined inwardly and downwardly to the intervening gutter and each having a longitudinal central row of perforations, flanges standing downwardly along the j outer edges of the plain side portions to support their elevated outer edges and to form a narrow seat and crush. joint at the outer edges of the batten on the face of said roof boards, and attaching nails driven through said perforations into said boards to spring the plain side portions flatwise to elastically retain the batten seated on said crush joints.

2. In a roof construction, fixedly attached roof boards spaced apart, in combination with a sheet-metal batten having a portion bent to form a central longitudinal open gutter on its face and a corresponding curved-sided wedge-shaped rigid rib on its back, said rib forced into the space between the fixed boards to crush the adjacent sharp angles thereof and form water-tight joints at both sides, plain side portions of the batten disposed at both sides of the gutter, and attaching nails driven through said side portions into the fixed boards.

3. A roof batten, comprising a sheet-metal strip ha ing a portion bent to form a central longitudinal open gutter on its face and a corresponding rigid wedge-shaped rib on its back, said rib adapted to be forced into a space between two fixed roof boards to crush the adjacent sharp angles thereof and form e' plain portions and .the thin flange edges adapted to seat on the face of a the roof boards to form crush water-tight joints thereon, the perforations of the inclined plain portions adapted to receive ataching nails driven through into the subjacent roof boards to spring said plain portions flatwise to elastically retain the batten seated against said crush joints.

at. A sheet-metal roof batten, comprising a single strip having a portion bent to form a curved open gutter along the longitudinal center of the face of the batten and to form a corresponding rigid wedge-shaped rib on the back of the batten adapted to-be driven into a space between two roof boards to crush the inner upper angles thereof and form crush-joint seats on both boards, and plain 'iongitudinal side portions at the sides of said gutter adapted to be nailed to the face of the subjacent boards.

5. A roofing batten, comprising a sheetmetal strip having a portion bent to form a longitudinal central open gutter in the face of the batten and a corresponding rigid rib of wedge-shaped cross-section with outward curves at the base of the wedge on the back of the batten adapted to be forced into the space between two roof boards to crush the adjacent sharp angles thereof and form water-tight joints with both boards.

In testimony whereof I have affixed my signature.
